Abstract

The invention concerns a tyre designed to be mounted on a mounting rim comprising rim seats (11) sloping outwards. Said tyre comprises beads (1) designed to urged into contact with the mounting rim, each bead having a circumferential reinforcing element serving as anchor to a carcass reinforcement, said element having a center of rotation about which said element can rotate when the bead is being mounted on the rim. Said bead has an outer profile (8) which, viewed in meridian cross-section, comprises a part forming a seat (81) for the bead, a side wall (83) and a connecting profile (82) between the seat and the side wall, at least one bead being such that the maximum distance L1 from the center of rotation of the bead reinforcing element to the points of the lateral profile (82) of the bead and the minimum distance L0 from the center of rotation of the reinforcement of the bead circumferential reinforcement to the points of the lateral profile (83) of the bead satisfy the following relationship: K < 1 %, with K = (L1-L0)/L1. The invention also concerns a method for making a tyre bead profile.
